Referring now to FIGS. 39-41, exploded views of all of the elements of the connector 300 (i.e., of the male portion 320 and the female portion 350) are shown. FIG. 39 shows a side view of all of the elements of the connector 300, as described above with reference to FIGS. 35-38. FIG. 40 shows a side perspective view of all of the elements of the connector 300, as described above with reference to FIGS. 35-38. FIG. 41 shows a top perspective view of all of the elements of the connector 300, as described above with reference to FIGS. 35-38.

Referring now to FIGS. 42-44, operation of the connector 300 is illustrated. FIG. 42 shows a side view of the male portion 320 and the female portion 350, as rotationally oriented with respect to one another in a manner that will allow engagement therebetween. Referring now to FIG. 42, in some embodiments, the wave ring 328 of the male portion 320 includes at least one peak 330 (i.e., a portion of the wave ring 328 that is furthest from the magnet 322) and at least one valley 332 (i.e., a portion of the wave ring 328 that is closest to the magnet 322). In some embodiments, the wave ring 358 of the female portion 350 includes at least one valley 360 (i.e., a portion of the wave ring 358 that is closest to the magnet 352) and at least one peak 362 (i.e., a portion of the wave ring 358 that is furthest from the magnet 352). In some embodiments the male portion 320 and female portion 350 are positioned for engagement when the at least one peak 330 of the wave ring 328 of the male portion 320 is aligned with the at least one valley 360 of the wave ring 358 of the female portion 350 and the at least one valley 332 of the wave ring 328 of the male portion 320 is aligned with the at least one peak 362 of the wave ring 358 of the female portion 350.

Referring now to FIG. 43, the male portion 320 and female portion 350 are shown rotationally oriented as in FIG. 42, and moved toward one another so as to engage one another. As shown in FIG. 43, the at least one peak 330 of the wave ring 328 of the male portion 320 is aligned with the at least one valley 360 of the wave ring 358 of the female portion 350 and the at least one valley 332 of the wave ring 328 of the male portion 320 is aligned with the at least one peak 362 of the wave ring 358 of the female portion 350. As a result of moving the male portion 320 and the female portion 350 toward one another, the at least one peak 330 of the wave ring 328 of the male portion 320 is located within the at least one valley 360 of the wave ring 358 of the female portion 350 and the at least one peak 362 of the wave ring 358 of the female portion is located within the least one valley 332 of the wave ring 328 of the male portion 320. Consequently, the magnet 322 of the male portion 320 is located in proximity to the magnet 352 of the female portion 350, retaining the male portion 320 in proximity to the magnet 350. In some embodiments, the magnet 322 of the male portion 320 and the magnet 352 of the female 350 generate magnetic fields of sufficient strength such that, when the male portion 320 and the female portion 350 are positioned as shown in FIG. 43, the male portion 320 and the female portion cannot be pulled away from one another in an axial direction (i.e., in a direction toward the orientation shown in FIG. 42). In some embodiments, the magnet 322 of the male portion 320 and the magnet 352 of the female 350 generate magnetic fields of sufficient strength such that, when the male portion 320 and the female portion 350 are positioned as shown in FIG. 43, the male portion 320 and the female portion cannot easily be pulled away from one another in an axial direction (i.e., in a direction toward the orientation shown in FIG. 42).

FIG. 44 shows a side view of the male portion 320 and the female portion 350 as rotationally oriented with respect to one another in a manner that will allow engagement therebetween. More particularly, in some embodiments, as shown in FIG. 44, the male portion 320 and female portion 350 are positioned for disengagement when the at least one peak 330 of the wave ring 328 of the male portion 320 is aligned with the at least one peak 362 of the wave ring 358 of the female portion 350 and the at least one valley 332 of the wave ring 328 of the male portion 320 is aligned with the at least one valley 360 of the wave ring 358 of the female portion 350. When the male portion 320 and the female portion 350 are so positioned, the at least one peak 362 of the wave ring 358 of the female portion 350 abuts the at least one peak 330 of the wave ring 328 of the male portion 320, preventing the male portion 320 from further approaching the female portion 350 and preventing the magnet 322 of the male portion 320 from engaging the magnet 352 of the female portion 350. As a result, the male portion 320 can be freely moved away from the female portion 350.

In some embodiments, to disengage the connector 300 when the male portion 320 is engaged with the female portion 350 (as shown in FIG. 43), a user rotates a device to which the male portion 320 is attached with respect to a device to which the female portion is attached. When such rotation is performed, the wave ring 328 of the male portion 320 and the wave ring 358 of the female portion 350 act as a cam, converting such rotation to linear motion of the male portion 320 apart from the female portion 350. Such motion generates a distance between the conductive magnet housing 324 of the male portion 320 and the conductive magnet housing 354 of the female portion 350, thereby opening an electrical circuit that was closed by contact between the conductive magnet housing 324 of the male portion 320 and the conductive magnet housing 354 of the female portion 350. Additionally, such motion increases a distance between the magnet 322 of the male portion 320 and the magnet 352 of the female portion 350, thereby reducing the magnetic attractive force generated between the magnet 322 of the male portion 320 and the magnet 352 of the female portion 350 and enabling the male portion 320 and the female portion 350 to be easily moved away from another in opposition to the resulting magnetic attractive force. In some embodiments, the magnet 322 of the male portion 320 and the magnet 352 of the female portion 350 cooperate to generate a magnetic attractive force of sufficient strength such that, when the male portion 320 and the female portion 350 are positioned as shown in FIG. 43, the male portion 320 and the female portion 350 cannot easily be pulled apart from one another, and such that, when the male portion 320 and the female portion 350 are positioned as shown in FIG. 44, the male portion 320 and the female portion 350 can easily be pulled apart from one another.

In some embodiments, the wave ring 328 of the male portion 320 and the wave ring 358 of the female portion 350 are capable of 360 degree rotation with respect to one another. In a default position at zero degrees, the wave ring 358 and the wave ring 328 complement each other, with the at least one peak 330 of the male portion 320 aligned with the at least one valley 360 of the female portion 350 and the at least one peak 362 of the female portion 350 aligned with the at least one valley 332 of the male portion 320 (i.e., as shown in FIG. 42). FIG. 2 shows an example of a default position of zero degrees. In some embodiments, in a position at 90 degrees, the wave ring 358 and the wave ring 328 complement each other, with the at least one peak 330 of the male portion 320 aligned with the at least one valley 360 of the female portion 350 and the at least one peak 362 of the female portion 350 aligned with the at least one valley 332 of the male portion 320 (i.e., as shown in FIG. 42). FIG. 8 shows an example of a position of 90 degrees. In some embodiments, in positions at 180 degrees and 270 degrees, the wave ring 358 and the wave ring 328 complement each other, with the at least one peak 330 of the male portion 320 aligned with the at least one valley 360 of the female portion 350 and the at least one peak 362 of the female portion 350 aligned with the at least one valley 332 of the male portion 320 (i.e., as shown in FIG. 42). In some embodiments, at intervals of 45 degrees between the aligned positions noted above (i.e., at 45 degrees, 135 degrees, 225 degrees, and 315 degrees), the wave ring 358 and the wave ring 328 do not complement each other, with the at least one peak 330 of the male portion 320 aligned with the at least one peak 362 of the female portion 350 and the at least one valley 360 of the female portion 350 aligned with the at least one valley 332 of the male portion 320 (i.e., as shown in FIG. 44). It will be apparent to those of skill in the art that the specific combinations of angles noted above (i.e., complementary positions offset from one another by 90 degrees, with noncomplementary positions offset from one another by 90 degrees and from complementary positions by 45 degrees) is only exemplary and that other combinations of angles are possible without departing from the broader principles described above.

Referring now to FIGS. 27-31B, an exemplary embodiment of a connector 400 is shown. The connector 400 includes a male portion 410 and a female portion 430. The connector 400 operates in a manner similar to that of the connector 300 other than as will be described hereinafter.

In some embodiments, the center contact 412 and the ring contact 414 are fixed to the non-conductive magnet housing 416 by another suitable engagement mechanism. In some embodiments, the non-conductive magnet housing 416 prevents the center contact 412 and the ring contact 414 from electrical contact with one another. In some embodiments, the non-conductive magnet housing 416 retains the center contact 412 and the ring contact 414 in relative positions such that, when the male portion 410 engages the female portion 430, the center contact 412 contacts at least one of the contacts 434 of the female portion 430 and the ring contact 414 contacts a different at least one of the contacts 434 of the female portion 430.
